ok so if its petrol u would tune it around 12:1 for power and 17:1 for economy..
what about LPG? they are two completely different fuels, im thinking u can go heaps richer than pet but not really sure....ive had it as lean as 20:1 it still runs but the power loss is very noticeable....unsure of how rich I can go for max power

I did read somewhere recently that 16:1 is the recommended A/F ratio for lean cruise. Anything leaner than that is considered to be putting your engine at risk from overheating. Don't want to melt those pistons.

Don't want to melt those pistons. thats right but thats for petrol...lpg doesnt seem to have a problem going lean (up to a point)
